I want to calculate the area for each polygon region in my table, and add this to a field/column.
Solution
- Open the Table and navigate to Table>Maintenance>Table Structure and add an field called Area of type Float.
- Then navigate to Table>Update Column.
- Select the Table as both the Table to Update and Table to get value from. Select the Area as the column to update.
- Click the Assist button. Select Area from the Function list and click OK.
- Click OK to update the table.
- Note that functions such as sum and average can be viewed by opening Options>Show Statistics Window. This displays the statistics for the current selection.
